If you can identify the early indicators of a twin pregnancy, your family will have the opportunity to prepare mentally and physically for their journey ahead.

There is no way of knowing for sure that you are carrying twins until a doctor confirms that you are carrying multiples. However, some signs indicate that you may be having a multiple birth. This article will highlight the signs of a twin pregnancy, the reasons why these signs exist, discuss the risk factors for being pregnant with multiples, and provide a guideline to seek medical assistance if you think that you are pregnant with twins.

What is a twin pregnancy?

Having twins means that you have two babies inside your body. Having twins can happen for different reasons. It could be because your family has twins, or you may have conceived with twins through fertility treatment.

Different Types of Twin Pregnancy

There are 2 types of twin pregnancies: fraternal twins (dizygotic) and identical twins (monozygotic). Fraternal twins occur when two separate eggs are fertilised by two different sperm. They may look the same or different. Fraternal twins each have their own amniotic sac and placenta. Identical twins are created when one fertilised egg divides into two embryos. They usually share the same placenta and may share the same amniotic sac, but this is not always the case. Identical twins will always be the same gender (either both boys or both girls).

Early signs of a twin pregnancy

Many women expecting twins will notice some signs of carrying multiples earlier and with greater intensity than they would in a singleton pregnancy. Some of these signs may include increased fatigue and morning sickness. The following are some of the most common early signs of twin pregnancies.

While many women associate morning sickness with the beginning stages of pregnancy, the severity of nausea and vomiting associated with twins can be much greater than that of those who are only pregnant with one baby.
Fatigue during pregnancy is normal; however, fatigue from carrying two babies may feel more extreme. When a woman is pregnant with two babies, her body has to work harder to grow both babies, which creates more strain on her system and leads to fatigue.
Pregnancy makes you hungry, but when you are pregnant with twins, that feeling of hunger can be even greater, and you may eat more often than a woman pregnant with a single baby.
Your breasts may be more tender or sore during a twin pregnancy than during a singleton pregnancy, and they may also become larger.
Some women who are carrying twins may begin to feel fetal movements much earlier in the pregnancy than a woman who is only pregnant with one baby.
Increased levels of the hormone hCG (human chorionic gonadotropin) can signal to health-care professionals that the mother may be pregnant with two or more babies.
Many women who are pregnant with twins notice that their symptoms are more severe than when pregnant with a single fetus. Symptoms such as excessive vomiting, increased urination, and overall discomfort tend to be increased when a woman is carrying twins; furthermore, women may experience chest pain and/or shortness of breath while at rest as their bodies attempt to provide sufficient oxygen for the growing babies.
When a woman is pregnant, her belly will continue to grow over time. However, when a woman is pregnant with twins, her belly may grow more quickly than average.

Risks of a twin pregnancy

Many twins born healthy and without any issues also have a higher risk of having complications during pregnancy than singleton babies. Common risks include:

Preterm labour and delivery
Gestational diabetes
Preeclampsia (high blood pressure)
Low birth weight
Fetal growth restriction

If you have questions or concerns about your pregnancy or about being pregnant with twins, please talk to your physician. Your physician will closely monitor you during the entire course of your pregnancy to ensure that both babies are healthy.

How to Care for a Twin Pregnancy?

If you believe you may be pregnant with twins, early pregnancy care will be even more crucial than if you were pregnant with just one child.

Proper prenatal care during the first trimester is essential to ensure your unborn child grows and develops healthily. Twin gestations are considered to be higher risk than single gestations; therefore, it is necessary to adhere to your doctor's instructions.
You should begin scheduling more frequent appointments with your medical provider to monitor the progress of your two fetuses. Ultrasounds and blood tests at regular intervals may be ordered during your visit to track each baby's development and rule out any problems.
You may need additional testing to identify potential complications that could arise from having two babies at once.
Adhering to healthy lifestyle choices may help support your pregnancy as you carry two babies. Eating a balanced diet, drinking plenty of fluids, and engaging in regular physical activity are all beneficial for your health; however, you may need to adjust your physical activity based on how you feel.
It is equally important to ensure you get adequate rest and avoid overexertion, as the physical demands of carrying multiple babies can be quite taxing.

Conclusion

Early pregnancy symptoms are not the same for every woman. Moreover, women with twins are likely to experience much higher levels of symptoms compared to a single child-bearing mother. This is because a woman’s hormone levels are considerably higher, placing greater demands on her body and, in turn, producing a more intense set of symptoms. An ultrasound is the only definitive method to confirm or deny the presence of twin pregnancies. If you suspect that you may be pregnant with twins, schedule an appointment with your physician to be assessed and receive appropriate care at your earliest opportunity.

Frequently Asked Questions

What is the difference between twins and singletons in terms of pregnancy?

With twin pregnancies, the mother will have a noticeable “bump” very early on.

What is the length of a full-term pregnancy for twins?

For most pregnancies that result in twin births, the average length is thirty-five to thirty-six weeks as opposed to the thirty-seven-week average in a singleton pregnancy.

Will fetal movements differ between twins and singletons?

Often, mothers of twins will feel much stronger fetal movements and will sometimes feel them in different parts of their abdomen.

Can first-time mothers of twins clearly identify the symptoms of a twin pregnancy?

Yes, but first-time mothers may not have as clear a picture of what a twin pregnancy feels like compared to women who have given birth to multiple children.

Can symptoms alone confirm a twin pregnancy?

Although symptoms may suggest that a woman is carrying twins, only an ultrasound can definitively determine whether or not there are twins in the womb.
